A computationally efficient multigrid control volume method based additivecorrection strategy is developed for the solution of the very high bearing number and shaped rail air bearing problems.
Using this way to set up bias-correction confidence belt is driven with data completely, and has not any additive regulating parameter, it is very effective in practical application.
The additive constant of the electro-optical distancemeasuring instrument and the total station instrument are the correction of the survey results using these instruments.
